Custom circular SeekBar for Android

Custom circular SeekBar for Android


Custom circular SeekBar (Circle, Semi-circle, and Ellipse) for Android.

This library is based on CircularSeekBar of Matt Joseph (devadvance).

The reason for create a repositive instead of fork it from Matt's, is that the project structure is different.

I make this library run on Android Studio (Gradle), and fix & add more features to the library.


The features I add

  1. Support float progress, instead of integer only.
  2. Refactor the name of the attributes, to avoid conflicts.
  3. Disable the seek pointer, make it work like a circular progress bar.
  4. Some other bug fixes for Matt's CircularSeekBar.
  5. Customize the shape of progress end (butt, round, square)
  6. Use a arc to represent the pointer, you can custom the arc angle.
  7. Negative progress support.

How to use


dependencies {
    compile 'me.tankery.lib:circularSeekBar:1.1.5'
